Valid compressor fuse location

[Bryan Beamon]

Our auxiliary compressor is pulsating every few minutes . Does anyone know what the fuse location is in the front run bay? This problem started when the night time temperatures dropped below 32 degrees

Bryan,
I'm pretty sure it's F-50 onthe PCB in the front elec bay. Sounds like the compressor or check valve might be bad.

Thanks Steve, I will try that fuse when the temperature drops.
I checked my wiring diagram and it does not identify F50 fuse, just curious how you knew that fuse controlled the compressor.

2007 Contessa Wiring Diagrams in Coach Assist. First 8 pages or so are fuse id and PCB layout. If F50 isn't it, I'd suspect an inline.

I found the fuse location for the Valid air compressor and it was identified as chassis battery and was F20 with a 20 amp fuse. Maybe this could help others or by process of elimination you could identified the location in any coach.

Like they say, RVs are like snowflakes, all different.. The list in Coach Assist came from Monaco. Go figure... I'll verify mine is wired the same and update the list as needed.

Bryan, we have has the same problem.  The compressor was new as was the pressure sensor valve.  I reliever the pressure to drain the tank which should be found it your engine compartment.  This seemed to clear the line and tank allowing the valve to function or so it seems. 
My bucket list has a trip to Salmon Arm BC and a good service at Valid.

Kieth, Valid tech support suggested removing the check valve on their air tank and replace with a straight through fitting. The rational was that the check valve senses air pressure in the air line not the air tank and thus would reduce the frequent running of the compressor. Which probably confirms that I have a air leak before the air tank.
